SEPARABLE BOOK.

SPECIFICATION formingpart of- Letters Patent N 0. 664.544, datedDecember 25, 1900. Application filed February 15, 1897- Reuewed April14, 1893. Serial No. 677,625. O OdBL) T at whom it may concern.-

Be it known that I, FRANKLIN HOWARD GIL- SON, of Wellesley, in thecounty of Norfolk and State of Massachusetts, have invented certain newand useful Improvements in Separable Books, of which the following is aspecification.

This invention relates to an album or the like having a series ofremovable leaves and a cover connected thereto.

One ofthe objects of the invention is to provide an improvedconstruction of the cover, whereby the same is rendered extensible andcapable of including any number of leaves within certain limits.

The invention consists in the improvements which I shall now proceed todescribe and claim.

Of the accompanying drawings, forming part of this specification, Figure1 is a perspective view of an album-cover embodying my invention, thecover being shown opened out and the leaves removed. Fig. 2 isaperspective view of the album or book complete.

Fig. 3 is a similar view to Fig. 2, showing a larger number of leavesinside the cover. Fig. 4 is a similar view to Fig. 1, showing a modifiedform of my invention. Fig. 5 is a section on line 5 5 of Fig. 2, andFig. 6 is a detail view showing a modification of my invention.

The same letters of reference indicate the same parts in all thefigures.

In the drawings, a a represent the front and back lids of my improvedcover, the two lids being substantially similar and constructed of anysuitable material. Each lid is provided at its rear edge with anextension comprising a number of separated parallel o flexible strips ortongues b b of cloth, leather, or other suitable flexible material. Thestrips of each lid alternate with those of the other lid and are adaptedto slide in the spaces of the other.

When the leaves 0 c are inserted in the album, the strips 1) lie flatagainst the lids a of the cover, and the exposed portions of the saidstrips constitute a continuous back for the album. The said back may belengthened to accommodate a large number of leaves, as shown in Fig. 3,or may be reduced to the dimension of a few leaves, as shown in Fig. 2,or even to one leaf or none at all. This reduction in width is notaccompanied by bulging of the back, the slack portion being taken up bysimply drawing the strips attached to each lid farther up under theopposite lid. Each set of strips 1) b may, if desired, be joined acrosstheir outer ends, thus furnishing a limit to the extensibility of theback. The strips 1) b may be of any desired number. There may be twowide strips in onesection, and one strip in the other, lying between thetwo, or there may be a larger number of narrower strips or the stripsmay be replaced by a large number of close-lying cords or strings. Theremay also be spaces between neighboring strips in the back. A furthermodification of the invention could be made by attaching each set ofstrips 1) to both lids of the cover, one attachment being made by meansof elastic connections between the ends of the strips and the lid, asshown in Fig. 6, which would serve to automatically keep the back frombulging. In fact, there are many modifications of structure which wouldproperly come within the scope of my invention. In my improved album thepack of leaves 0 c and cover a a are bound together and the said leavesretained in place by means of a cord d, which passes around or throughand engages a series of slots formed at opposite points on the top andbottom edges of the said leaves near the inner or rear ends thereof, thesaid slots being arranged to coincide with each other and withcorresponding slots at, Figs. 1 and 2, or orifices (1 Figs. 3 and 4., inthe edges of the cover-lids an. The employment of slots a in the saidlids in conjunction with the slots 0 of the leaves permits of a readyassembling or separation of the parts and also permits of the use of acontinuous binding-cord, such as an elastic rubber band, Fig. 2. Theslots a and c are preferably formed with a narrow neck portion, forminga constricted passage for the cord or band, a wider cord-receivingportion or eyelet, and a widened or flaring entrance to guide the cordto the neck portion, as shown. Owing to the formation of the slots withconstricted or nar- I00 row necks, the fastening-cord is prevented frommoving laterally or slipping out of the enlarged inner portions of theslots when the cord is loosened for thepurpose of removing or insertingone or more leaves. Hence the cord is retained in position to readilyenter the slots of a newly-inserted leaf and does not require the amountof manipulation that would be necessary if the cord were free to slipout of the slots of leaves which are not to be disturbed.

In Fig. 4 longitudinal slots 1) are shown in the edge strips, and inthis case the cord 01 is discontinuous, its ends being laced through theslots 12 in assembling and tied together, as shown in Fig. 3.

My invention is applicable not only to photograph-albums, but to anyother separable book of this nature, such as a sample-book for holdingsamples of cloth and other merchandise.

I claim- 1. A book-or album cover comprising two lids, and an adjustablebackcomposed of two sections, one attached to each lid, said sectionshaving alternating strips or tongues separated by spaces, the tongues ofeach section being adapted to slide in the spaces of theother.

2. A leaf for abook or album, havingin its top and bottom edges near itsinner end, slots to receive an encircling fastening band or cord, eachslot having a flaring mouth or entrance, a narrow neck adapted toprevent the escape of the cord when loose, anda wide rear portion toreceive the band or cord.

3. A book or album leaf, comparatively thick and unyielding atits innerend and having slots in the top and bottom edges of its inner end, saidslots each having a flaring mouth, a constricted neck, and an enlargedinner portion, whereby when a cord or band is forced through said neckinto the inner portion it is constricted by the unyielding walls thereofand prevented from slipping laterally out of the inner portion whenloose.

4. A book or album comprising two lids, a series of leaves interposedtherebetwcen, said lids and leaves having slots formed in their top andbottom edges near their inner ends, said slots each having a flaringmouth, a contracted neck, and an enlarged inner portion, and acompressible band or cord encircling the inner ends of said lids andleaves and lying in the inner portions of said slots, the saidconstricted neck retaining the cord in the enlarged inner portion of theslot when the cord is loose.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 5th day of February, A. D.1897.

FRANKLIN HOWARD GILSON.
